Switch from Docopt to Clap.
There were two important reasons for the switch:
1. Performance. Docopt does poorly when the argv becomes large, which is
a reasonable common use case for search tools. (e.g., use with xargs)
2. Better failure modes. Clap knows a lot more about how a particular
argv might be invalid, and can therefore provide much clearer error
messages.
While both were important, (1) made it urgent.
Note that since Clap requires at least Rust 1.11, this will in turn
increase the minimum Rust version supported by ripgrep from Rust 1.9 to
Rust 1.11. It is therefore a breaking change, so the soonest release of
ripgrep with Clap will have to be 0.3.
There is also at least one subtle breaking change in real usage.
Previous to this commit, this used to work:
rg -e -foo
Where this would cause ripgrep to search for the string `-foo`. Clap
currently has problems supporting this use case
(see: https://github.com/kbknapp/clap-rs/issues/742),
but it can be worked around by using this instead:
rg -e [-]foo
or even
rg [-]foo
and this still works:
rg -- -foo
This commit also adds Bash, Fish and PowerShell completion files to the
release, fixes a bug that prevented ripgrep from working on file
paths containing invalid UTF-8 and shows short descriptions in the
output of `-h` but longer descriptions in the output of `--help`.

ripgrep's default regex engine uses finite automata and guarantees linear
|
|
|
|
time searching. Because of this, features like backreferences and arbitrary
|
|
|
|
look-around are not supported. However, if ripgrep is built with PCRE2, then
|
|
|
|
the --pcre2 flag can be used to enable backreferences and look-around.

ripgrep supports configuration files. Set RIPGREP_CONFIG_PATH to a
|
|
|
|
configuration file. The file can specify one shell argument per line. Lines
|
|
|
|
starting with '#' are ignored. For more details, see the man page or the

README.

Switch from Docopt to Clap.
There were two important reasons for the switch:
1. Performance. Docopt does poorly when the argv becomes large, which is
a reasonable common use case for search tools. (e.g., use with xargs)
2. Better failure modes. Clap knows a lot more about how a particular
argv might be invalid, and can therefore provide much clearer error
messages.
While both were important, (1) made it urgent.
Note that since Clap requires at least Rust 1.11, this will in turn
increase the minimum Rust version supported by ripgrep from Rust 1.9 to
Rust 1.11. It is therefore a breaking change, so the soonest release of
ripgrep with Clap will have to be 0.3.
There is also at least one subtle breaking change in real usage.
Previous to this commit, this used to work:
rg -e -foo
Where this would cause ripgrep to search for the string `-foo`. Clap
currently has problems supporting this use case
(see: https://github.com/kbknapp/clap-rs/issues/742),
but it can be worked around by using this instead:
rg -e [-]foo
or even
rg [-]foo
and this still works:
rg -- -foo
This commit also adds Bash, Fish and PowerShell completion files to the
release, fixes a bug that prevented ripgrep from working on file
paths containing invalid UTF-8 and shows short descriptions in the
output of `-h` but longer descriptions in the output of `--help`.
Fixes #136, Fixes #189, Fixes #210, Fixes #230

Switch from Docopt to Clap.
There were two important reasons for the switch:
1. Performance. Docopt does poorly when the argv becomes large, which is
a reasonable common use case for search tools. (e.g., use with xargs)
2. Better failure modes. Clap knows a lot more about how a particular
argv might be invalid, and can therefore provide much clearer error
messages.
While both were important, (1) made it urgent.
Note that since Clap requires at least Rust 1.11, this will in turn
increase the minimum Rust version supported by ripgrep from Rust 1.9 to
Rust 1.11. It is therefore a breaking change, so the soonest release of
ripgrep with Clap will have to be 0.3.
There is also at least one subtle breaking change in real usage.
Previous to this commit, this used to work:
rg -e -foo
Where this would cause ripgrep to search for the string `-foo`. Clap
currently has problems supporting this use case
(see: https://github.com/kbknapp/clap-rs/issues/742),
but it can be worked around by using this instead:
rg -e [-]foo
or even
rg [-]foo
and this still works:
rg -- -foo
This commit also adds Bash, Fish and PowerShell completion files to the
release, fixes a bug that prevented ripgrep from working on file
paths containing invalid UTF-8 and shows short descriptions in the
output of `-h` but longer descriptions in the output of `--help`.
Fixes #136, Fixes #189, Fixes #210, Fixes #230

The format of the flag is `{type}:{attribute}:{value}`. `{type}` should be

one of path, line, column or match. `{attribute}` can be fg, bg or style.
|
|
|
|
`{value}` is either a color (for fg and bg) or a text style. A special format,

`{type}:none`, will clear all color settings for `{type}`.
|
2018-02-03 07:37:52 +02:00

the background color for line numbers to yellow:

rg --colors 'match:fg:magenta' --colors 'line:bg:yellow' foo.

|
2018-02-11 05:48:46 +02:00

Extended colors can be used for `{value}` when the terminal supports ANSI color
|
2018-02-03 07:37:52 +02:00
|
|
|
sequences. These are specified as either 'x' (256-color) or 'x,x,x' (24-bit
|
2018-02-10 20:02:48 +02:00
|
|

truecolor) where x is a number between 0 and 255 inclusive. x may be given as
|
|

a normal decimal number or a hexadecimal number, which is prefixed by `0x`.
|
2018-02-03 07:37:52 +02:00
|

For example, the following command will change the match background color to

that represented by the rgb value (0,128,255):

|
|
|
|
|
|

rg --colors 'match:bg:0,128,255'

rg --colors 'match:bg:0x0,0x80,0xFF'
|
|
|
|

When this flag is provided, ripgrep will emit a sequence of messages, each
|
|
|
|
encoded as a JSON object, where there are five different message types:
|
|
|
|
|
|
|
|
**begin** - A message that indicates a file is being searched and contains at
|
|
|
|
least one match.
|
|
|
|
|
|
|
|
**end** - A message the indicates a file is done being searched. This message
|
|
|
|
also include summary statistics about the search for a particular file.
|
|
|
|
|
|
|
|
**match** - A message that indicates a match was found. This includes the text
|
|
|
|
and offsets of the match.
|
|
|
|
|
|
|
|
**context** - A message that indicates a contextual line was found. This
|
|
|
|
includes the text of the line, along with any match information if the search
|
|
|
|
was inverted.
|
|
|
|
|
|
|
|
**summary** - The final message emitted by ripgrep that contains summary
|
|
|
|
statistics about the search across all files.
|
|
|
|
|
|
|
|
Since file paths or the contents of files are not guaranteed to be valid UTF-8
|
|
|
|
and JSON itself must be representable by a Unicode encoding, ripgrep will emit
|
|
|
|
all data elements as objects with one of two keys: 'text' or 'bytes'. 'text' is
|
|
|
|
a normal JSON string when the data is valid UTF-8 while 'bytes' is the base64
|
|
|
|
encoded contents of the data.
|
|
|
|
|
|
|
|
The JSON Lines format is only supported for showing search results. It cannot
|
|
|
|
be used with other flags that emit other types of output, such as --files,
|
|
|
|
--files-with-matches, --files-without-match, --count or --count-matches.
|
|
|
|
ripgrep will report an error if any of the aforementioned flags are used in
|
|
|
|
concert with --json.
|
|
|
|
|
|
|
|
Other flags that control aspects of the standard output such as
|
|
|
|
--only-matching, --heading, --replace, --max-columns, etc., have no effect
|
|
|
|
when --json is set.

When multiline mode is enabled, ripgrep will lift the restriction that a match
|
|
|
|
cannot include a line terminator. For example, when multiline mode is not
|
|
|
|
enabled (the default), then the regex '\\p{any}' will match any Unicode
|
|
|
|
codepoint other than '\\n'. Similarly, the regex '\\n' is explicitly forbidden,
|
|
|
|
and if you try to use it, ripgrep will return an error. However, when multiline
|
|
|
|
mode is enabled, '\\p{any}' will match any Unicode codepoint, including '\\n',
|
|
|
|
and regexes like '\\n' are permitted.
|
|
|
|
|
|
|
|
An important caveat is that multiline mode does not change the match semantics
|
|
|
|
of '.'. Namely, in most regex matchers, a '.' will by default match any
|
|
|
|
character other than '\\n', and this is true in ripgrep as well. In order to
|
|
|
|
make '.' match '\\n', you must enable the \"dot all\" flag inside the regex.
|
|
|
|
For example, both '(?s).' and '(?s:.)' have the same semantics, where '.' will
|
|
|
|
match any character, including '\\n'. Alternatively, the '--multiline-dotall'
|
|
|
|
flag may be passed to make the \"dot all\" behavior the default. This flag only
|
|
|
|
applies when multiline search is enabled.
|
|
|
|
|
|
|
|
There is no limit on the number of the lines that a single match can span.
|
|
|
|
|
|
|
|
**WARNING**: Because of how the underlying regex engine works, multiline
|
|
|
|
searches may be slower than normal line-oriented searches, and they may also
|
|
|
|
use more memory. In particular, when multiline mode is enabled, ripgrep
|
|
|
|
requires that each file it searches is laid out contiguously in memory
|
|
|
|
(either by reading it onto the heap or by memory-mapping it). Things that
|
|
|
|
cannot be memory-mapped (such as stdin) will be consumed until EOF before
|
|
|
|
searching can begin. In general, ripgrep will only do these things when
|
|
|
|
necessary. Specifically, if the --multiline flag is provided but the regex
|
|
|
|
does not contain patterns that would match '\\n' characters, then ripgrep
|
|
|
|
will automatically avoid reading each file into memory before searching it.
|
|
|
|
Nevertheless, if you only care about matches spanning at most one line, then it
|
|
|
|
is always better to disable multiline mode.

|
|
|
|
When PCRE2 matching is enabled, this flag will disable Unicode mode, which is
|
|
|
|
otherwise enabled by default. If PCRE2 matching is not enabled, then this flag
|
|
|
|
has no effect.
|
|
|
|
|
|
|
|
When PCRE2's Unicode mode is enabled, several different types of patterns
|
|
|
|
become Unicode aware. This includes '\\b', '\\B', '\\w', '\\W', '\\d', '\\D',
|
|
|
|
'\\s' and '\\S'. Similarly, the '.' meta character will match any Unicode
|
|
|
|
codepoint instead of any byte. Caseless matching will also use Unicode simple
|
|
|
|
case folding instead of ASCII-only case insensitivity.
|
|
|
|
|
|
|
|
Unicode mode in PCRE2 represents a critical trade off in the user experience
|
|
|
|
of ripgrep. In particular, unlike the default regex engine, PCRE2 does not
|
|
|
|
support the ability to search possibly invalid UTF-8 with Unicode features
|
|
|
|
enabled. Instead, PCRE2 *requires* that everything it searches when Unicode
|
|
|
|
mode is enabled is valid UTF-8. (Or valid UTF-16/UTF-32, but for the purposes
|
|
|
|
of ripgrep, we only discuss UTF-8.) This means that if you have PCRE2's Unicode
|
|
|
|
mode enabled and you attempt to search invalid UTF-8, then the search for that
|
|
|
|
file will halt and print an error. For this reason, when PCRE2's Unicode mode
|
|
|
|
is enabled, ripgrep will automatically \"fix\" invalid UTF-8 sequences by
|
|
|
|
replacing them with the Unicode replacement codepoint.
|
|
|
|
|
|
|
|
If you would rather see the encoding errors surfaced by PCRE2 when Unicode mode
|
|
|
|
is enabled, then pass the --no-encoding flag to disable all transcoding.

A preprocessor is not run when ripgrep is searching stdin.
|
|
|
|
|
|
|
|
When searching over sets of files that may require one of several decoders
|
|
|
|
as preprocessors, COMMAND should be a wrapper program or script which first
|
|
|
|
classifies FILE based on magic numbers/content or based on the FILE name and
|
|
|
|
then dispatches to an appropriate preprocessor. Each COMMAND also has its
|
|
|
|
standard input connected to FILE for convenience.
|
|
|
|
|
|
|
|
For example, a shell script for COMMAND might look like:
|
|
|
|
|
|
|
|
case \"$1\" in
|
|
|
|
*.pdf)
|
|
|
|
exec pdftotext \"$1\" -
|
|
|
|
;;
|
|
|
|
*)
|
|
|
|
case $(file \"$1\") in
|
|
|
|
*Zstandard*)
|
|
|
|
exec pzstd -cdq
|
|
|
|
;;
|
|
|
|
*)
|
|
|
|
exec cat
|
|
|
|
;;
|
|
|
|
esac
|
|
|
|
;;
|
|
|
|
esac
|
|
|
|
|
|
|
|
The above script uses `pdftotext` to convert a PDF file to plain text. For
|
|
|
|
all other files, the script uses the `file` utility to sniff the type of the
|
|
|
|
file based on its contents. If it is a compressed file in the Zstandard format,
|
|
|
|
then `pzstd` is used to decompress the contents to stdout.
|
|
|
|
|
|
|
|
This overrides the -z/--search-zip flag.

This flag works in conjunction with the --pre flag. Namely, when one or more
|
|
|
|
--pre-glob flags are given, then only files that match the given set of globs
|
|
|
|
will be handed to the command specified by the --pre flag. Any non-matching
|
|
|
|
files will be searched without using the preprocessor command.
|
|
|
|
|
|
|
|
This flag is useful when searching many files with the --pre flag. Namely,
|
|
|
|
it permits the ability to avoid process overhead for files that don't need
|
|
|
|
preprocessing. For example, given the following shell script, 'pre-pdftotext':
|
|
|
|
|
|
|
|
#!/bin/sh
|
|
|
|
|
|
|
|
pdftotext \"$1\" -
|
|
|
|
|
|
|
|
then it is possible to use '--pre pre-pdftotext --pre-glob \'*.pdf\'' to make
|
|
|
|
it so ripgrep only executes the 'pre-pdftotext' command on files with a '.pdf'
|
|
|
|
extension.
|
|
|
|
|
|
|
|
Multiple --pre-glob flags may be used. Globbing rules match .gitignore globs.
|
|
|
|
Precede a glob with a ! to exclude it.
|
|
|
|
|
|
|
|
This flag has no effect if the --pre flag is not used.

include directive. The include directive permits specifying one or more other

--type-add 'src:include:cpp,py,md'

Additional glob rules can still be added to the src type by using the

|
--type-add flag again:
|
|
|
|
|
|
|
|
--type-add 'src:include:cpp,py,md' --type-add 'src:*.foo'
|
|
|
|

Punctuation characters are not allowed.

Switch from Docopt to Clap.
There were two important reasons for the switch:
1. Performance. Docopt does poorly when the argv becomes large, which is
a reasonable common use case for search tools. (e.g., use with xargs)
2. Better failure modes. Clap knows a lot more about how a particular
argv might be invalid, and can therefore provide much clearer error
messages.
While both were important, (1) made it urgent.
Note that since Clap requires at least Rust 1.11, this will in turn
increase the minimum Rust version supported by ripgrep from Rust 1.9 to
Rust 1.11. It is therefore a breaking change, so the soonest release of
ripgrep with Clap will have to be 0.3.
There is also at least one subtle breaking change in real usage.
Previous to this commit, this used to work:
rg -e -foo
Where this would cause ripgrep to search for the string `-foo`. Clap
currently has problems supporting this use case
(see: https://github.com/kbknapp/clap-rs/issues/742),
but it can be worked around by using this instead:
rg -e [-]foo
or even
rg [-]foo
and this still works:
rg -- -foo
This commit also adds Bash, Fish and PowerShell completion files to the
release, fixes a bug that prevented ripgrep from working on file
paths containing invalid UTF-8 and shows short descriptions in the
output of `-h` but longer descriptions in the output of `--help`.
Fixes #136, Fixes #189, Fixes #210, Fixes #230
